The details of the study conducted on the synthesis and characterization of nanosized Titanium dioxide (TiO2) particles and their application on cotton and polyester/cotton fabrics for imparting multifunctional properties (viz. Antibacterial protection, self-cleaning and UV protection) are reported in this paper. Titanium dioxide (TiO2) is extensively used as a photocatalyst due to the strong oxidizing power of its holes, high photo-stability and redox selectivity.The nano-particles of TiO2 were produced in different conditions of temperature (100° or 120°C) and the concentration of HNO3 using soft chemistry. These nano-particles were characterized by Fourier transformed infrared spectroscopy (FTIR), transmission electron microscopy (TEM), and Xray powder diffractometry (XRD) for assessing the composition, their shape, size and crystallinity respectively. Then, these TiO2 nano-particles were applied to 100%cotton and polyester/cotton samples to impart multifunctionality to the treated textiles. The effectiveness of the multifunctional finishing treatment was assessed through standardized tests available for testing the special functions such as anti-microbial protection, selfcleaning and UV protection both before and after washing of the treated samples. Consequently, it was demonstrated that the finished 100% cotton and polyester/cotton fabrics with nano TiO2 had various functionalities, such as antimicrobial activity, self-cleaning and UV protection. The results of these tests have been collected, studied, analyzed and reported here.Keywords

Due to the increasing demand for fossil fuels and environmental threat due to pollution a number renewable sources of energy have been studied worldwide. In the present investigation influence of injection timing on the performance and emissions of a single cylinder, four stroke stationary, variable compression ratio, diesel engine was studied using cottonseed oil (CSO) as the biodiesel blended with diesel. Experimental investigation on the Performance parameters and Exhaust emissions from the engine were done. Artificial neural networks (ANNs) were used to predict the engine performance and emission characteristics of the engine. Separate models were developed for performance parameters as well as emission characteristics. To train the network compression ratio, blend percentage, percentage load and injection timings were used as the input variables whereas engine performance parameters and engine exhaust emissions were used as the output variables. Experimental results were used to train ANN.
